Overview
Diagnostic Study of Choice
Gold standard/Study of choice:
- Liver biopsy is the gold standard test for the diagnosis of autoimmune hepatitis[1][2][3][4]
- Liver biopsy is performed by following methods:
- Percutaneous liver biopsy with or without ultrasound guidance
- Transjugular liver biopsy
Histology findings usually found on biopsy:
- Interface hepatitis (ie, piecemeal necrosis) is the histological hallmark
- Portal lesion spares the biliary tree
- This involves most of the lobule
- Lobular collapse which is best identified by reticulin staining
- There is lymphoplasmacytic periportal infiltrate which invade the limiting plate
- There is an abundance of plasma cells and eosinophils are usually present
- A plasma cell infiltrate lead to plasma cell hepatitis If it involves lobules called lobular or whole liver known as panacinar hepatitis
In cirrhosisfollowing findings are seen on biopsy:
Overlap syndrome
Liver biospy is gold standard for diagnosing overlap syndrome[5][6]
